ALBERT H. IVALKER, OF HARTFORD, CONNECTICUT.

PROJECTOR FOR SEA-OILING SHELLS.

SPECIFICATION forming part of Letters Patent No. 381,733, dated April24, 1888.

Application filed February 29, 1888. Serial No. 265,692. (No model.)

To all whom it may concern:

Be it known that I, ALBERT H. \VALKER, of Hartford, Connecticut, haveinvented a new and useful Projector for Sea-Oiling Shells, of which thefollowing description and claims constitute the specification, and whichis illustrated by the accompanying sheet of drawings.

This projector is adapted to throw from a ship into the sea such aseaoiling projectile as that described and claimed in my applica tionNo. 260,024, filed January 7, 1888, for Letters Patent of the UnitedStates of America.

Figure 1 of the drawings is a view of the projector clasped in the righthand. of a sailor and clasping the projectile between its forward ends.Fig. 2 is a view, partly in section, of what is shown in the upper partof Fig. 1. Fig. 3 is a section on the dotted line of Fig. 2. Fig. 4 is across-section of the projector on the plane of the mutual axis of thetwo parts thereof and looking toward the projectile. Fig. 5 is afragmentary view of the middle portion of the two levers whichconstitute the principal part of the projector, with the nut and boltwhich unite them removed, so as to exhibit their mutual articulation.Fig. 6 is a central vertical section of the projectile.

The letters A and B indicate the two levers which constitute theprincipal parts of the projector. The rear ends of those levers arepreferably made in the form of the rear ends of the two members oftailors shears, and they are pivoted together by the bolt C and aresecured in position by the nut D and a corresponding head on the otherend of the bolt. The strap E may be employed, if desired, to guardagainst the danger of the projector slipping from the hand of the sailorand flying into the sea. The forward parts of the levers A and B areprovided with the dowelsocket F and the dowel G, respectively, to insureidentity of plane in the mutually-approaching movement of the forwardparts of the levers. Those forward parts are also provided with theconcave wings H and I, respectively,which wings are prefcrabl y madeintegral with the dowel socket and dowel, respectively, and serve tosecure the easy and certain placing of the projectile at precisely theproper place in the projector. The forward ends of the levers A and Bare provided with inwardlyprojecting prongs J and K, respectively,whichprongs are firmly fixed in the blocks L and M, respectively, and whichblocks are provided with exterior screw-threads for engagement withcorrespondinginterior screw-threads in the cylindrical recesses N and Oin the lovers A and B, respectively. The strippers P and Q reciprocatein those cylindrical recesses, respectively, and that reciprocation iscaused by the spiral springs R and S, respectively, and is limited bythe annular flanges T and U, respectively, which flanges arerespectively integral with the outer cylindrical part of the respectivestrippers. The two concentric cylindrical parts of the two strippers areunited by an integral annular part, as shown in the drawings, and theannular spaces between those concentric annular parts constitute therecesses for the springs R and S, respectively.

\Vhen the filled projectile of Fig. 6 is to be thrown into the sea, itis impaled between the forward ends of the levers A and B in theposition shown in Figs. 1, 2, and 3. Then the sailor grasps the rearends of the levers, as shown in Fig. 1, and swings his arm as if he wereabout to throw or toss a ball, and at the instant his arm reaches itsutmost stretch he opens his hand so as to separate the rear ends of thelevers A and B and also to separate the forward ends of those levers,and thus extract the prongs J and K from the openings which they made inthe disks 2 and 6, respectively. That extraction, which might otherwisebe limited to one of those prongs, is insured to both of them by thestrippers P and Q,which strippers are forced toward the ends of theprongs J and K, respectively, by the springs R and S, respectively. Thusliberated from the projector, the projectile is hurled into the sea.

I do not herein claim the projectile which I describe and show, becauseI describe and claim that projectile in my application No. 260,024,filed January 7, 1888, for Letters Pat ent of the United States ofAmerica.

I claim as my invention- 1. A projector for sea-oiling shells,consisting of the levers A and B, crossing each other and mutallyarticulated midway of their lengths and pivoted together by the bolt C,and provided at their forward parts with the dowel socket F and thethereiirentering dowel G, respectively, the meeting wings H and I,

respectively, and the axially-opposite and inwardly-projecting prongs Jand K, respectively, all substantially as described.

2. A projector for sea-oiling shells, consisting of the levers A and B,crossing each other and mutually articulated midway of their lengths andpivoted together by the bolt G, and provided at their forward parts withthe axially opposite and inwardlyprojecting prongs J and K,respectively, the strippers P and Q, respectively, adjacent to thoseprongs, and the springs R and S, adjusted to work those strippers,respectively, all substantially as described.

3. A projector for sea oiling shells, consisting of the levers A and B,crossing each other ALBERT H. WALKER.
